What could i do with my testpipe. The one flange is busted off. My car is an 86 and doesn't have a flange on the wastegate pipe. How Could I make this so I can bolt this up and go. Would a V Band clamp be a good idea?

I'd just sawzall that broken piece off and put a lap band clamp on it. Should be <$10.

That is the first time I have ver seen that kind of failure.

I want to be able to bolt this up and unbolt it when I have emissions testing and what not. So a way that woudn't make it reversible would be great.

Burch testpipes come with a cheap paint coating that comes off in no time resulting in rust. I have one for my 86 that is the non-flange type that uses a crush ring.

You don't have to remove the test pipe, just buy a slip in cat. A lot easier!

I would take it to an exhaust shop and see if they can help you. They should be able to remove that flange, and give you another to slip on the other piece. Or just chop it and use one of those exhuast clamps that slip over the tubing that you can buy at Napa, Autozone, etc. It's just the wastegate, it isn't 100% imperative to have good seal.

Whats a slip in cat?

PorscheDoc

If you need to swap it in and out for emissions inspections, I would just take the stock pipe off, hollow out the cat chamber with a big long bipe and hammer, and reinstall it. That way it will look stock with just no internals in it. You don't want to be bolting and unbolting that pipe from the turbo downpipe alot, that is asking for trouble with broken studs, etc.

I didn't realize your test pipe has a permanent cat delete section. Most come with it as a separate slip on piece. As Doc said, you don't want to be removing that piece all the time, if not for the PITA it is, but for studs as stated. Get a different test pipe (that way it is in way better condition and you also have the option to run a cat for emissions testing).

Would it be stupid to have some flanges put in where the cat is and then have a place make a small testpipe?

Darwantae951

The least headache route would be to buy a new or used testpipe.

I would like to clarify that emission testing is done once every 2 years. Its just a visual inspection. So I don't know if I would have to swap in a cat as the car is getting old enough that they may not care. I bought this testpipe thinking that I could use it. I would like to use it if possible, but if not then I may just have a shop make a custom testpipe on that could be swapped just for the cat converter.

Mine has a flared end (no flange unless it was cut off perhaps) and I used a band clamp and it had a donut gasket in there. Kinda weird, probably a kluge from a PO, but it works OK.
